About This Topic

The Great Lakes and Water Security focuses on the management and protection of the world's largest freshwater system. Students explore the geographic, economic, and environmental importance of the Great Lakes to both Canada and the United States. This topic is a vital case study in international cooperation and the challenges of protecting a shared resource.

Students will investigate the primary threats to the health of the Great Lakes, including pollution, invasive species, and the impacts of climate change. They will also look at the debate over whether water should be treated as a human right or a commodity to be sold. This topic comes alive when students can use real-world data and collaborative investigations to analyze the health of the lakes and propose solutions for their long-term security.

Active Learning Ideas

Watch Out for These Misconceptions

Common MisconceptionThe Great Lakes are so big that they can't be significantly harmed by pollution.

What to Teach Instead

Because the Great Lakes are a closed system with a slow turnover of water, pollutants can build up and stay in the system for a long time. Using a 'bioaccumulation' model can help students see how even small amounts of toxins can harm the entire food web.

Common MisconceptionWater security is only a problem for dry, desert countries.

What to Teach Instead

Even in water-rich regions like the Great Lakes, water security is threatened by pollution, aging infrastructure, and competing demands for use. A 'local water audit' can help students see that water security is a concern for everyone.

Frequently Asked Questions

Why are the Great Lakes so important?
The Great Lakes contain about 20% of the world's surface fresh water. They provide drinking water for over 40 million people, support a massive fishing and shipping industry, and are home to a unique and diverse ecosystem.
What are the biggest threats to the Great Lakes today?
The main threats include pollution from industrial and agricultural runoff, the spread of invasive species that disrupt the food web, and the impacts of climate change, which are causing unpredictable changes in water levels and temperatures.
How do Canada and the U.S. work together to manage the lakes?
The two countries work through organizations like the International Joint Commission (IJC) and agreements like the Great Lakes Water Quality Agreement. These help them coordinate research, set pollution limits, and manage water levels and diversions.
How can active learning help students understand water security?
Active learning, such as the debate on selling water, helps students engage with the ethical and political dimensions of resource management. By researching invasive species or pollution data, they see the 'science' of the lakes in action, making the concept of 'security' much more than just a word in a textbook.
